Have to say the CEL did go out immediately but it took almost a week and a half for the system to give a green light on the OBDII code reader. It can take a while for the OBD II to report a state of readiness. For anyone trying to get this to pass emmissions.......be patient, it's not the car it's the logic required by OBDII... It needs to make sure the fix is permanent.

Do you know if you have to drive your car around? or, would it be enought just to let it run (idle)? and how many miles or hours do you think it took to clear the code out? thank you.
